如何在Linux/Unix系统中创建名称含"/"的目录？

Hey there! Let's cut to the chase: you can't create a directory with a real "/" character in its name on any Linux distro (including SUSE). The "/" is hardcoded as the system's path separator at the kernel level—any attempt to use it directly will just be interpreted as a new directory level, not part of the filename.

But if you need something that looks like a "/" in the directory name, here are the go-to workarounds specifically for this scenario:

1. Use a Full-Width Slash (U+FF0F) #

This is the closest visual match to a regular slash, and the system doesn't treat it as a path separator. You can either:

• Switch your keyboard to full-width mode and type it directly, or
• Generate it via printf if you're working in a script or don't have full-width input enabled:

  # Direct input (full-width slash)
  mkdir "reports／2024-q3"
  # Generate via Unicode escape
  mkdir "$(printf 'project\uFF0Fv2')"
  

Pros: Looks identical to a regular slash at a glance.
Cons: Requires careful input—accidentally using a regular slash will create nested directories instead.

2. Use a Fraction Slash (U+2215) #

This is a mathematical fraction slash that's visually similar but slightly more distinct. It's great if you want to avoid accidentally mixing it up with real path separators:

mkdir "$(printf 'src\u2215utils')"

Pros: Less likely to be confused with a real path separator than full-width slashes.
Cons: Still requires special input or printf to generate.

3. Fall Back to a Safe Alternative (Most Reliable) #

If visual similarity isn't critical, using an underscore, hyphen, or another non-special character is the safest bet. It avoids all ambiguity and works with every tool/script out there:

mkdir "project_v2"
mkdir "src-utils"

Pros: 100% compatible with all Linux utilities and scripts—no surprises.
Cons: Doesn't look like a slash.

Important Note #

Don't waste time trying to escape the regular "/" with backslashes (\) or quotes. Commands like mkdir "foo/bar" or mkdir foo\/bar will just create a bar directory inside a foo directory—they won't create a single directory named foo/bar. The kernel will always interpret "/" as a path separator, no matter how you escape it in the shell.
